However, for 64-bit architectures it isn\u0027t sufficient\nto return 32 bits of time_t; this isn\u0027t good insurance against the 2037\nrollover. (It also makes glibc support less convenient, since we can\u0027t\nuse glibc\u0027s handy STAT_IS_KERNEL_STAT mode.)\n\nThis change extends the two \"timespec\" fields for each of the three atime,\nmtime, and ctime fields from \"int\" to \"long\". As a result, on 32-bit\nplatforms nothing changes, and 64-bit platforms will now work as expected.\n\nThe only wrinkle is 32-bit userspace under 64-bit kernels taking advantage\nof COMPAT mode. For these, we leave the \"struct stat64\" definitions with\nthe \"int\" versions of the time_t and nsec fields, so that architectures\ncan implement compat_sys_stat64() and friends with sys_stat64(), etc.,\nand get the expected 32-bit structure layout. This requires a\nfield-by-field copy in the kernel, implemented by the code guarded\nunder __ARCH_WANT_STAT64.\n\nThis does mean that the shape of the \"struct stat\" and \"struct stat64\"\nstructures is different on a 64-bit kernel, but only one of the two\nstructures should ever be used by any given process: \"struct stat\"\nis meant for 64-bit userspace only, and \"struct stat64\" for 32-bit\nuserspace only. (On a 32-bit kernel the two structures continue to have\nthe same shape, since \"long\" is 32 bits.)\n\nThe alternative is keeping the two structures the same shape on 64-bit\nkernels, which means a 64-bit time_t in \"struct stat64\" for 32-bit\nprocesses. This is a little unnatural since 32-bit userspace can\u0027t\ndo anything with 64 bits of time_t information, since time_t is just\n\"long\", not \"int64_t\"; and in any case 32-bit userspace might expect\nto be running under a 32-bit kernel, which can\u0027t provide the high 32\nbits anyway. In the case of a 32-bit kernel we\u0027d then be extending the\nkernel\u0027s 32-bit time_t to 64 bits, then truncating it back to 32 bits\nagain in userspace, for no particular reason.

return as well.\n\nUntil now, the tile architecture ABI for syscall return has just been\nthat r0 holds the return value, and an error is only signalled like it is\nfor kernel code, with a negative small number.\n\nHowever, this means that in multiple places in userspace we end up writing\nthe same three-cycle idiom that tests for a small negative number for\nerror. It seems cleaner to instead move that code into the kernel, and\nset r1 to hold zero on success or errno on failure; previously, r1 was\njust zeroed on return from the kernel (to avoid leaking kernel state).\nThis way a single conditional branch after the syscall is sufficient\nto test for the failure case. The number of cycles taken is the same,\nbut the error-checking code is in just one place, so total code size is\nsmaller, and random userspace syscall code is easier to understand.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "c745a8a11fa1df6078bfc61fc29492ed43f71c2b", "tree": "2db1cdf9cd0d0e892f4f92de1fd2700ac319f04a", "parents": [ "1fcbe027b5d29ec9cd0eeb753c14fb366ae852ac" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:52:19 2010 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:52:19 2010 -0400" }, "message": "arch/tile: Various cleanups.\n\nThis change rolls up random cleanups not representing any actual bugs.\n\n- Remove a stale CONFIG_ value from the default tile_defconfig\n- Remove unused tns_atomic_xxx() family of methods from \u003casm/atomic.h\u003e\n- Optimize get_order() using Tile\u0027s \"clz\" instruction\n- Fix a bad hypervisor upcall name (not currently used in Linux anyway)\n- Use __copy_in_user_inatomic() name for consistency, and export it\n- Export some additional hypervisor driver I/O upcalls and some homecache calls\n- Remove the obfuscating MEMCPY_TEST_WH64 support code\n- Other stray comment cleanups, #if 0 removal, etc.\n\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "1fcbe027b5d29ec9cd0eeb753c14fb366ae852ac", "tree": "b0d80646567ac71238cf2ffb33e29ad33d758816", "parents": [ "32020effaf713c0c669864301bcd5dac6b9bb9e0" ], "author": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:40:57 2010 -0400" }, "committer": { "name": "Chris Metcalf", "email": "cmetcalf@tilera.com", "time": "Fri Aug 13 08:40:57 2010 -0400" }, "message": "arch/tile: support backtracing on TILE-Gx\n\nThis functionality was stubbed out until recently.

Subrectangles of the chip can\nbe allocated by a \"create\" ioctl on /dev/hardwall, and then to access the\nUDN in that rectangle, tasks must perform an \"activate\" ioctl on that\nsame file object after affinitizing themselves to a single cpu in\nthe region. Sending a wormhole-routed message that tries to leave\nthat subrectangle causes all activated tasks to receive a SIGILL\n(just as they would if they tried to access the UDN without first\nactivating themselves to a hardwall rectangle).\n\nThe original submission of this code to LKML had the driver\ninstantiated under /proc/tile/hardwall.

As such, we are using a device rather\nthan, for example, a syscall, to set up and activate this code.\n\nAs part of this change, the compat_ptr() declaration was fixed and used\nto pass the compat_ioctl argument to the normal ioctl.
